发明名称 Light-emitting element including a light-emitting stack with an uneven upper surface
摘要 A light-emitting element includes: a light-emitting stack including an uneven upper surface; a transparent conductive layer formed on the uneven upper surface; an insulating layer formed on the transparent conductive layer and filling the uneven upper surface, and partial regions of the transparent conductive layer are exposed; a reflective layer formed on the transparent conductive layer and the insulating layer; and a contact interface including a current blocking area formed between the insulating layer and the reflective layer and a plurality of first contact regions formed between the transparent conductive layer and the reflective layer; and an electrode structure formed on the reflective layer, and the reflective layer is between the light-emitting stack and the electrode structure in a vertical direction of the light-emitting element; wherein the current blocking area and the plurality of first contact regions are coplanar.
